Diagnosis. Macropterous ♀ of Anteon  with colour almost completely black; head granulate and reticulate rugose; mesoscutum granulate, except unsculptured surface near anterior margin; forewing with two dark transverse bands; pronotum with posterior surface much shorter than mesoscutum; propodeal declivity rugose, without longitudinal keels; protarsomere 4 about 0.5 × as long as basal part of 5.

Description. ♀. Fully winged ( Fig. 66View FIGURE 66); body length 2.2 mm. Head black, except mandible testaceous; antenna testaceous, except antennomeres 6–10 darkened; mesosoma black; metasoma brown; legs testaceous, except meso- and metacoxa, clubs of meso- and metafemur, meso- and metatibia brownish. Antenna clavate; antennomeres in following proportions: 12:4:5:4:4:5:5:5:5:7. Head slightly convex, dull, granulate and reticulate rugose; frontal line complete; frons with two lateral keels near orbits directed towards antennal toruli; occipital carina complete; POL = 6; OL = 3; OOL = 5; OPL = 5; TL = 5; greatest breadth of lateral ocelli shorter than OPL (3:5). Pronotum anteriorly crossed by slight transverse impression, dull, granulate, with anterior surface rugose and posterior surface sculptured by longitudinal keels; posterior surface much shorter than mesoscutum (5:16), slightly shorter than anterior surface (5:7); border between anterior and posterior surface marked by transverse carina; pronotal tubercle reaching tegula. Mesoscutum dull, completely granulate, except anterior surface near pronotum shiny and unsculptured. Notauli very shortly visible near anterior margin of mesoscutum. Mesoscutellum shiny, unsculptured. Metanotum dull, sculptured by many longitudinal keels. Metapectal-propodeal disc with strong transverse posterior keel, dull, reticulate rugose; propodeal declivity dull, reticulate rugose, without longitudinal keels. Forewing with two dark transverse bands; distal part of 2r-rs&Rs vein much shorter than proximal part (4:8). Protarsomeres in following proportions: 5:2:2:4:16. Enlarged claw ( Fig. 67CView FIGURE 67) with proximal prominence bearing one long bristle. Protarsomere 5 ( Fig. 67CView FIGURE 67) with basal part about as long as distal part, twice as long as protarsomere 4 (8:4), with one row of 7 lamellae; apex with about 7 lamellae. Tibial spurs 1/1/2.
